The Superior Marathon and Trail Machine.

First prototypes and pre-production samples had to proof themselves in competitive racing - but now the brandnew Jura Carbon ES Di2 is ready for your fun rides and races to victory. With a light and stiff full carbon frame, new electronic XT Di2 drivetrain and many other high-class components. With 27.5" or 29" wheels depending on frame size. And 100% ready for marathon/XC races and fast trail riding.

Rearshock Development

Diffferent purposes in different terrain require different ride properties. This is why every fully rear triangle receives a specific setup from STEVENS' engineers to meet the respective bike's requirement for optimum performance. Firm for minimum power loss in the marathon with lots of comfort for long distance riding with a linear characteristic curve and mind-soothing reserves for hard hits.

Boost-Standard Fork

What is right for the rear wheel is even more important at the front wheel - because steering precision matters. This is why STEVENS uses suspension forks and hubs with extra wide axle spacing for all its 29er fullies, the Whaka+ ES and the trail rocket Sonora SL. These 110mm of axle spacing are called "Boost" or "Plus" and stand for lots of added lateral stiffness plus space for extra wide studded tires.

Side Swing front derailleur

Our top supplier Shimano made a great innovation here. One that works reliably on any terrain when changing gears at the front has to be fast and precise - be it in competitions or on technical trails. Thanks to its upright axes the front derailleur cage swings outward and forward at the same time, and due to its direct actuation from the downtube only needs minimum operating force.

High Modulus Carbon Fibers

Only the very best materials are used for the highest quality STEVENS carbon frames - so called high modulus carbon fibres. They offer a perfect combination of maximum toughness and elasticity. This way they provide maximum lateral stiffness for best forward drive and a high amount of comfort. Result: incredibly light and enormously stiff frames.

Versatile cable routing

We keep the cable routing on our bikes as versatile as possible so you can ride your bike like you want to. There are wide and therefore easy to reach cable ports in the frame to insert either one or two cables or none at all - there are cover plugs for any of these configurations. This is also very convenient for retrofitting a dropper post.

Tapered Steerer / Tapered Headtube

Fork shaft (or steerer tube) and head tube are tapered, meaning their diameter increases from top to bottom resulting in a conical shape. The diameter needs to be bigger at the bottom since this is where higher stress is applied - especially when the bike has a higher total weight due to luggage or an e-drive and battery. Also tapered steerers feature a smoother force transfer (like forces caused by hard braking) to the downtube than forks with a continuous 1 1/8" diameter.
